CMHC Mortgage Insurance Premium Calculator
Enter a home price, a down payment and an amortization, and see the CMHC mortgage loan insurance premium, the premium added to the mortgage, and the total mortgage. This is an estimate only, using CMHC's premium schedule for a purchase with a traditional down payment source. It is not financial advice and it approves nothing.

The purchase price. Mortgage loan insurance is available only on homes priced at $1.5 million or less.
Your down payment in dollars, from a traditional source such as savings. Borrowed (non-traditional) down payments carry a higher premium in the highest band, which this calculator does not use.
An amortization over 25 years adds 0.20 percentage points to the premium rate. Insured 30-year amortizations are limited to first-time buyers and buyers of newly built homes.
How the estimate works
When insurance is required. Mortgage loan insurance is required when the down payment is less than 20% of the price and the price is $1.5 million or less. At 20% down or more, no premium is charged in this estimate; CMHC's schedule also lists rates at 80% loan-to-value and below for cases where a lender insures a conventional mortgage, which are not used here.
The premium table (premium on the total loan amount, amortization up to 25 years). Loan-to-value over 95%: not insurable. 90.01% to 95%: 4.00%. 85.01% to 90%: 3.10%. 80.01% to 85%: 2.80%. An amortization over 25 years adds 0.20 percentage points in each band.
Minimum down payment. 5% of the first $500,000 of the price, plus 10% of the part above $500,000, up to $1.5 million. Homes at $1.5 million or more need at least 20% down and cannot be insured.
Amortization. The standard maximum for an insured mortgage is 25 years. Since December 15, 2024, first-time buyers and buyers of newly built homes can choose 30 years.
What this calculator leaves out. Provincial sales tax on the premium, non-traditional down payment premiums, rental and multi-unit properties, and lender fees.
